Ingredients

  • 2 tsp baking powder
  • 250 g plain flour
  • 250 g unsalted butter
  • 250 g caster sugar
  • 4 large eggs
  • 3 teaspoons vanilla extract
  • ¼ cup buttermilk 60ml
  • Frosting
  • 280 g cream cheese
  • 140 g unsalted butter
  • 1 ½ cups icing sugar
  • 1 tsp vanilla extract

Instructions

  • To make the frosting – whip together room temperature butter, vanilla extract and cream cheese using a hand mixer until thoroughly combined and smooth. Add the icing sugar in thirds, mixing well between each addition to ensure it gets thoroughly mixed in.
  • Cover and set aside in the fridge while you make the cake
  • Beat room temperature butter with the caster sugar in a stand mixer using the paddle attachment until light and fluffy and pale
  • Add one egg at a time and continue to mix. It is normal for the mixture to look split at this stage
  • Add the vanilla extract and the butter milk and mix
  • Add the sifted flour and baking powder in thirds, mixing well between each addition
  • Once the batter has come together, add to a well greased and lined baking tray and even out with a pallet knife
  • Bake at 180℃ for 30 minutes (see note) until a skewer comes out clean and the cake is golden
  • Let cool completely before spreading the frosting over the top
  • Add 2 tablespoons of sprinkles before cutting and serving

Notes

Note - if you use a larger baking tray the cooking time will be less. I recommend checking your cake after 20 minutes to see if it is close to being ready using a skewer. If it comes out clean, it is ready.
